Oatmeal Pie

Oatmeal Pie is a decadent vintage dessert that takes no time to make! This thick and gooey molasses pie is perfect for the holidays—it’s just like a pecan pie without nuts!

If you love pecan pie, you HAVE to try this Oatmeal Pie! It’s an old-fashioned dessert recipe just like grandma used to make. It has the consistency of a pecan pie  — minus the nuts — with an oatmeal topping. If you added some raisins, it would taste like a big, warm Oatmeal Raisin Cookie!

This recipe actually has a bit of history, too! Oatmeal pie dates back to the Civil War when pecans were hard to come by. It’s often called “poor man’s pecan pie,” but trust me, the taste is anything but poor! The filling is thick, gooey, and has that perfect molasses flavor that’ll make you feel like you’re eating an extra-rich oatmeal cookie in pie form.

Ingredients

The full printable recipe card with measurements and instructions is found at the bottom of the post.

• Eggs: Large eggs are usually the best choice when working with baking recipes. Pro tip: Let them sit on the counter while prepping other ingredients to warm to room temperature.
• Brown sugar: Adds sweetness and a hint of richness.
• Molasses: This gives the pie that deep, chewy flavor and dark color. Light molasses is ideal for this recipe; it gives the pie a rich but not overpowering flavor. Don’t use blackstrap molasses!
• Milk: You just need a little liquid to thin out this thick pie filling. My grandmother always used whole milk, but it’s possible plant-based milk could work here, too. Try it and let me know!
• Oatmeal: I like to use old-fashioned oats in my baking. They have a perfectly chewy texture but aren’t too hard to bite through.
• Butter: Melted butter adds richness and keeps the pie extra moist.
• Vanilla extract: You can’t skip vanilla! It adds that finishing touch.
• Frozen pie crust: I like using a pre-made pie crust for ease, but feel free to use homemade if you prefer!

Yes! Oatmeal pie freezes beautifully. Just bake, cool completely, wrap, and freeze for up to 2 months. Thaw and enjoy with a scoop of ice cream!

Recipe Tips and Tricks

Whether you’re new to this vintage dessert or have made it for decades, I’ve got some tips for the best oatmeal pie:

• Make it ahead of time. This pie is perfect for the holidays because you can make it in advance! Just cover it with foil. It will last up to three days in the fridge.
• Add toppings. When it’s time to serve this vintage oatmeal pie, there are so many garnishes you can add. I like a simple homemade whipped cream on mine, but vanilla ice cream, chocolate fudge sauce, or even a caramel drizzle is a great addition.
• Let it cool completely. While you may be tempted to cut into this delicious-smelling pie immediately, trust me—it’s worth the wait. If the pie is still hot, the filling flows like lava. It sets as it cools, so let it rest for at least 4 hours before serving.
• Add raisins. Do you love oatmeal raisin cookies? Make this into an oatmeal raisin pie! Add them to the filling for a chewy, fruity surprise in every bite!
